EL4501C - Preliminary

The EL4501C Video Front End (VFE) is an integrated solution that provides the key analog signal conditioning functions for analog video signals. It forms the front end interface for either an analog or ana-log/digital video system. The VFE contains a high bandwidth DC Restore, a sophisticated Sync Separator, and a Data Slicer for embed- ded data recovery.

The VFE will perform the restoration of the DC reference level (blanking level) and the extraction of all of the necessary timing sig-nals needed for synchronization and control. The sync separator is designed for very good noise immunity by incorporating a signal qual- ification scheme and internal brick wall filter. A data slicer is also included to help decode data embedded in the active video or VBI areas of the signal.

The VFE operates from a single 5 volt supply and is available in a small 24 pin QSOP package that takes only 0.08in²  (54mm² ) of board area, as well as a standard 24 pin SOIC.
